Prof. Wang is studying how bone cells sense external mechanical
forces, which allows living bone tissue to adapt to its mechanical
usage. With the absence of mechanical stimulation (such as the
microgravity for astronauts) and loss of sensitivities of detecting
the loads (such as during aging), bone mass decreases and bone
structure degenerates, eventually leading to bone fracture. recent
studies have found that osteocytes—the most abundant cells buried
inside the mineralized matrix—serve as sensors that orchestrate
In discussing the Lisbon Strategy, we pose the following question: why has the
Lisbon Agenda only limited success? One reason may be the institutional
setting. The high priority that is given to fiscal and monetary stabilisation
policies is reflected in the existence of sanctions if the members of the Euro
Area do not meet the Maastricht criteria. In contrast, the low priority given to
the Lisbon strategy can be seen in the absence of institutions to enforce the
achievement of targets.
Azoospermia is defined as the complete absence of spermatozoa upon examination of the
semen [including capillary tube centrifugation (CTC), strictly confirmed by the absence of
spermatozoa issued in urine after ejaculation]. The presence of rare spermatozoa
August 1st. Up very early, and by water to Whitehall to my Lord's, and there up to my Lord's lodging (Win.
Howe being now ill of the gout at Mr. Pierce's), and there talked with him about the affairs of the Navy, and
how I was now to wait today at the Privy Seal. Commissioner Pett went with me, whom I desired to make my
excuse at the office for my absence this day. Hence to the Privy Seal Office, where I got (by Mr. Mathews'
means) possession of the books and table, but with some expectation of Baron's bringing of a warrant from...
This examination of some of the compositions produced by Villa-Lobos over the 1910s reveals his
desire to take a stance in relation to Rio de Janeiro’s classical musicians. To be accepted by his
peers, he had to abide by the aesthetic rules of the classical music scene in the city. This included
moving away from popular music: it is striking that, in the body of work composed by Villa-Lobos
during the 1910s, there is an almost complete absence of aesthetic elements linked to popular music,
despite the composer’s contact with the chorões.
Although the annotation of the complete genome sequence ofMycoplasma
pneumoniaedid not reveal a bacterial type I signal peptidase (SPase I) we
showed experimentally that such an activity must exist in this bacterium, by
determining the N-terminus of the N-terminal gene product P40 of MPN142,
formerly called ORF6 gene. Combining mass spectrometry with a method
for sulfonating specifically the free amino terminal group of proteins, the
cleavage site for a typical signal peptide was located between amino acids 25
and 26 of the P40 precursor protein. ...
IN CHAPTER 5 WE DISCUSSED plants’ requirements for mineral nutrients and light in order to grow and complete their life cycle. Because living organisms interact with one another and their environment, mineral nutrients cycle through the biosphere. These cycles involve complex interactions, and each cycle is critical in its own right. Because the amount of matter in the biosphere remains constant, energy must be supplied to keep the cycles operational. Otherwise increasing entropy dictates that the flow of matter would ultimately stop.
Carrier Sense Multiple Access (CSMA) is a probabilisticMedia Access Control (MAC) protocol in which a node
verifies the absence of other traffic before transmitting on a shared transmission medium
CAN uses a nondestructive bitwise arbitration, which means that messages remain intact after arbitration is
completed even if collisions are detected. All the arbitration takes place without corruption or delay of the
message that wins the arbitration.
England’s fisheries in 1871, Congress created the U.S. Commission of Fish and Fisheries (Hobart 1995). The first appointed Commissioner, Spencer Baird, initiated marine ecological studies as one of his first priorities. According to Baird, our understanding of fish “... would not be complete without a thorough knowledge of their associates in the sea, especially of such as prey upon them or constitute their food....” He understood that the presence or absence of fish was related not only to removal by fishing, but also to the dynamics of physical and chemical oceanography.
Advertising is more complicated than it used to be. In the innocent days of the 70’s and 80’s you could easily reach large audiences, both locally and nationally, through traditional advertising. Those days are long gone and an examination of the advertising playing field looks like a big pile of incomprehensible choice. Let’s sort through it a bit, by separating advertising into two categories: online advertising and offline advertising.

Massive acute colonic pseudo-obstruction successfully managed with conservative therapy in a patient with cerebral palsy

Abstract Acute colonic pseudo-obstruction (ACPO), also known as Ogilvie syndrome, is a massive dilation of the colon in the absence of mechanical obstruction.

Defect symmetry influence on electronic transport of zigzag nanoribbons
Hui Zeng1,2*, Jean-Pierre Leburton2,3,4, Yang Xu5 and Jianwei Wei6
Abstract The electronic transport of zigzag-edged graphene nanoribbon (ZGNR) with local Stone-Wales (SW) defects is systematically investigated by first principles calculations.
Yet for all this there is no part of the subject where the established
results of analysis and experience have been so little systematized
and brought into relation with the main categories of theoretical
economics. Special monographs exist by the hundred. The pam-
phlet literature is so extensive as to surpass the power ofanyone man
completely to assimilate it. Yet in English, at any rate, there has
been so little attempt at synthesis of this kind that, when Mr.

The mechanisms of action of acupuncture are not
entirely clear. Although we have many pieces of this puzzle, it is still not complete
neither entirely mounted. Another debilitating element is the absence of a convincing
model of sham acupuncture for a control group in clinical trials. All this facts, allied to
inappropriate prejudice and unfamiliarity, reinforce the false notion that acupuncture
works mainly due to placebo effect.
It is remarkable to see the rapid increase in interest in the health of men since
the mid-1980s. We have moved from a position where there was almost
complete silence on the subject, an absence that was reflected not only in
policy and clinical practice but also within the academic community, to this
now being recognized as an area of major importance.
Tympanocentesis (needle aspiration through
the TM) and myringotomy (incision in the TM
to provide ﬂ uid) are the only methods directly
demonstrating the presence or absence of
middle ear effusion (Rosenfeld 1999). These
methods also have an immediate and posi-
tive effect on conductive hearing loss, which
in AOM may be as signiﬁ cant as 50 dB (Mar-
golis and Hunter 1991; Hunter et al. 1994).
Their role as diagnostic methods and treatment
modalities has changed completely during recent
To learn about the correlation between allostery and ligand binding of the
Tet repressor (TetR) we analyzed the effect of mutations in the DNA read-ing head–core interface on the effector specific TetR
variant. The same
mutations in these subdomains can lead to completely different activities,
e.g. the V99G exchange in the wild-type leads to corepression by 4-ddma-atc without altering DNA binding. However, in TetR
it leads to 4-ddma-atc dependent repression in combination with reduced DNA binding in
the absence of effector. ...
Radiological changes are found at the time of tuberculin conversion in 7-30% of young adults.•Lymphadenopathy. The hilarlymph node was most commonly involved but the paratrachealnode was also frequently enlarged.•Bilateral hilaradenopathymay be seen. In adults the lung component of the primary complex is usually more obvious and the nodal component may not be seen. •Radiological abnormality persists in a majority 6 months after diagnosis but complete resolution is usual after 2 years.
